DUnit: 'Global' SetUp and TearDown

Question

In DUnit, SetUp and TearDown are called before (and after, respectively) each test method is executed.
In SetUp, I create an object that loads data from a file. This is slow, especially if I have many tests.
Is there any way to call SetUp once, before executing ALL tests (and obviously the same for TearDown)?

Answer 1

From the documentation:

TTestSetup

TTestSetup can be used when you wish to set up state exactly once for a test case class (the SetUp and TearDown methods are called once for each test method). For example, if you were writing a suite of tests to exercise some database code, you might subclass TTestSetup and use it to open and close the database before executing the suite.
